METHOD or MARKING AND PERFOR ING SHEETS.

To'all whom it may concern:

Be it known that I, PAUL Bi; K UGH, a citizen of the United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented new and useful Improvements in Methods of Marking andPerforating Sheets, of which the following-is a full, clear, concise,; and eXact'descrip'tio'n, reference being had to the accompanying drawing, forming a part of thisspecificw tion. l J My invention relates to a method of marking and perforating sheets, and more specifically to the making of master-sheets for use in automatic perforating-machines for making music-rolls for automatic musical instruments.

One of the objects of my invention'is'to provide a method of marking and perforating these sheetswhich shall "be simple and direct and which can be'used in'the preparation of what are known as -.hand-played music-rolls, that is, music-rolls which will reproduce a selection according to" the players interpretation, rather than strict Further objects will appear from the detailed description to follow'and the appended claims.

In the drawings, in which I have illustrated apparatus for carrying out my method,

Figure 1 is a vertical section, showing part of a musical instrument, such as a grand piano, and showing alsoa recording-device, operatively connected with themusi'cal instrument, for making a record one mastersheet of a musical selection as itis being P y 1 a Fig. 2 is a vertical section, showing-"an automatic perforating machine, controlled by a perforated master-shetQfor use in making perforated note-sheets;

Fig. 3 is a face-view of a part of a mastersheet, made according to my invention, showing, in full lines, the marks made by the recording-device and showing, in dotted lines, the outlinesof the perforations which are to be made in th'e,mastersheet to'correspond to the markings, 1

corresponding recorded markings, and showing also-,in' sect1on,-certa1n of the readerfingers-whlch have dropped 1nto the perforation-s in the master-sheet, and showing also, in section, the spurs on the feed-wheel of the automatic perforating-machine.

In carrying out my method, the mastersheet is placed in position in the recordingdevlce, which is so connected with a musical instrument that, whena selection is played on the musical instrument, a record will be automatlcally marked on the master-sheet,

showing what notes were sounded and the dui'lation-of the notes. The master-sheet is then removed from the recording-machine and perforated in any suitable manner (as The Referring now to the drawings in detail, and first to the musical instrument and re- COIdiHg-dGVICB shown in Fig. 1, a musical instrument (indicated in general by v10"),

which maybe a grand piano and which has the usual black and white keys 11 and '12,

has suitably supported thereon a recordingdevice (indicated in general by 13), com

prising a frame 15 supportedon the instru ment 10 by means of legs 16 and l7,ap-laten -18 for supporting the master-sheet, and a pair of feed-rolls 19 and 20 for causing the master-sheet to travel over the platen 18. Supported on the frame 15, are a pair of standards 21, each having a pair of horizontal arms 22 and 23 for supporting crossbars 24 and 25, respectively, having guideopenings' 26 and 27, -respectively, in which are slidably mounted the markingdevices 28, which are provided with marking-points 29' for engaging the master-sheet as it travels beneath them. Coil-springs 30 surround the marking-devices 28 above the bar 25 and engage nuts31, threaded onthe upper end of the marking-devices, to'hold the markingdevices normally in raised position out of engagement with the master-sheet. The upper ends" of the marking devices 28 are located directly'beneath horizontal arms 32of -bell-crank-levers 33, which are .pivotally amounted one shaft 34, which extends transversely of the marking-device and is mount ed in vert cal extensions 35 of thestandards 21, Connected to the vertical arms 36 of the bell-cr-ank-levers 33, are cords 37, which extend through openings 38in a guide-plate 39 mounted on horizontal arms 40 extending from the standards 21. .The cords 37 extend farther, through guide openings 4:1 in aguide-plate 42, which is adj ustably mounted on a plate 43, extending across the front of the recording-device, by means of screws 4&1 extending through slots 45 in the plate 42.

The ends of the cords 37 are secured to screw-eyes 4-6 and 17, which are screwed into the keys 11 and 12.

The use and. operation of the recording- -device is'as follows: A master-sheet 50 is placed in position upon the platen 18 and in sponding marking-devices 28 to be depressed to bring the marking-points 29 into engage- .ment with the master-sheet, through the mstrumentality of the bell-crank-levers 33 and the cords 37. The extent of the recorded markings will correspond exactly to the duration of the corresponding notes. These markings are shown at. 51' in Figs. 3 and l.

' Either before or after the record has been made on the master-sheet, as above described, the master-sheet is provided with transverse markings 52, as shown in Figs. 3

and 4:, the distance betweenadjacent transverse markings being equal to the feed-step of the step-feed-device of an automatic perforating machine, which the 1naster-sheet is to control. The transverse markings 52 are for use as a guide in punching the mastersheet after it has been marked, so that'the ends of'the perforations in the master-sheet can be properly located with respect to the reader-fingers of the perforating-macliine,

with which the master-sheet is to be used. Either before or after the record is made on the master-sheet, it is also provided with a V series of holes 53 and 54: on its opposite edges for engagement with the spurs of the feedwheels of the automatio perforating-ma.- chme. After the record has been made on the master-sheet, as above described, it 1s perforated in substantial correspondence with the recorded markings, with this slight variation, however, that the perforations, instead of being exactly co-extensive with the recorded markings, are made so that their front ends coincide with those transverse inarkings 5.2 which I the retarded marina eat the ends of 5 5 i 'shis variance,

however, is so slight that it will be imperceptibleto the ear when the not-e sheets, prepared from the master-sheets, are played.

In practice, the master-sheet may travel about six inches per second, and the transverse marks on the "master sheet may be placed about 3,- of an inch apart, in which case, the distance between the transverse markings will correspond to of a second.

With such a spacing of the transverse markings, the front end of the recordedrmark on the record-sheet can never be more than of an inch distant from one of the transverse markings 52, so that the variation of .the front end of a perforation from the end .of a recorded mark should never be more than would correspond to of a second in the time of playing the selection. By this method of making master-sheets, the

individuality of the performer isbrought out, that is, the perforated master-sheet will correspond to the players interpretation of .the selection, rather than to the music as it is -wr1tten. Thus, 1n Figs. 3 and l,the music,

as written, may indicate that the notes, corresponding to the markings 51 shown, are to be sounded simultaneously and are to be of equal duration. As it was actually played, however, the record shows that certain of the notes were sounded before others, .and the sheet is punched to correspond to this marking.

After the master-sheet has been perforated, as above described, it is placed in a suitable automatic perforating machine. (such as thatshown 1n Flg. 2) which com- ..pr1ses a frame 55,0nwh1ch is supported a platen 56and in which are mounted a pair of feed-rolls 57 and 58 for causing the notesheets to travel over the platen 56. A feedwheel 59, for the master-sheet, is also mounted in the frame 55 and is provided With spurs 60 for engagement with the openings 53 and 54: of the master-sheet 50, as shown in 'A series of punches 61 are slidably mount ed in'openings 62 and 63 in the platen56 and guide-plate 64r,-respectively. The upper ends of these punches are positioned to. extend into openings65 in a die-plate 66, located above the platen 56. I A cross-bar is -mounted for vertical sliding movement in the frame 55 and is driven from the shaft .68 by means of a crank 69 and connecting rod 70. Mounted on the cross-bar 67, is a.

transverse rod 71, on which are pivotally mounted a-Vseries of punch-controlling-devices (indicated in general at 72), each comprising a horizontal arm' 7 3, provided with a reader 'finger 74 positioned in the line of I travel of the perforations in the mastersheet, andavertical arm 75 which enga es the low r end'off the punches 61 when L-llfi "Fit am s iiite opening, in

The reader fingers 'ii will ride on the master-sheet 50 until anope'ning 87 in the master-sheetco'inesintof position beneath a reader fiiigeii As'iong as the reader-fingersm ride on top of the mastersheet, the reciprocation ofthe cross bar will not cause the operation of any of the punches 61, as the arms 75 willnot be in position to engage the punches. When, however, a reader-finger 74: drops into an opening in the master-sheet, the corresponding arm 75 will move into position beneath one of the punches 61, and the subsequent reciprocation of the cross-bar 67 will cause the corresponding punch 61 to be raised to make perforations 1n the note-sheet 8-6.

ends of'the perforation-s 87 Will be properly positioned with 'respectto the reader-fingers "74, that is, the perforations Will either permic the "reader-fingers to enter freely, or the master-sheetivvillcompletely block the path "ofthereader-finger. I a

While, in some of the claims, certain steps of the method '(such as the making of the record on-the"master-sheet and the placing of the transverselines on the master-sheet) are 'recitedfin a certain order,-it is obvious that the steps of the methodneed not be carried ou't intheorder in which they are recited,as the transverse marks can be placed on'the master-sheet either before or after the Having thus described invention What chimes new and desireto secure by Letters Pate'ntis: i i will' be i 1.
